[iOS]UIView Animation

아이폰의 Animation을 사용하는 방법이다.

- Block을 이용하는 방법.

[UIView animateWithDuration:1.0

                          delay:0.0

                        options:UIViewAnimationOptionCurveEaseIn

                     animations:^(void) {

                         self.view.alpha = 0.0;

                     }

                     completion:^(BOOL finished) {

                         [UIView animateWithDuration:1.0

                                               delay:0.0

                                             options:UIViewAnimationOptionCurveEaseOut

                                          animations:^(void) {

                                              self.view.alpha = 1.0;

                                          }

                                          completion:nil];

                     }];

- beginAnimations, commitAnimations 를 이용하는 방법

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:1.5];

[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

[self.view setAlpha:0.0];

[UIView commitAnimations];

- frame을 조정

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:1.5];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

CGRect rect = self.view.frame;

CGRect goal = CGRectMake(rect.origin.x, rect.origin.y + 200, rect.size.width, rect.size.height);

[self.view setFrame:goal];

[UIView commitAnimations];

- AnimationCurve 옵션

UIViewAnimationCurveEaseInOut : 시작과 끝에는 천천히. 중간에는 빠르게.

UIViewAnimationCurveEaseIn : 처음에는 천천히. 진행할수록 빠르게.

UIViewAnimationCurveEaseOut : 처음에는 빨리. 진행할수록 느리게.

UIViewAnimationCurveLinear : 항상 일정한 속도로 진행된다.
